WINDOW-CHAIR.

Specification of Letters Patent.

PatentedJuly 27,1909.

Application filed September 21, 1908. Serial No. 454,051.

To all whom it may concern:

Be it known that 1, JOHN M. J. SKnLLY, a citizen of the United States,residing at Cleveland, in the county of'Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Window-Chairs, of whichthe following is a specification.

My invention relates to improvements in window-chairs for the use ofwindow cleaners, painters, and carpenters, enabling them to reach anyportion of the outside of a window in a perfectly safe and convenientmanner.

The primary object of the invention is to provide a generally improvedchair of this class, which will be exceedingly simple in construction,cheap of manufacture, and eflicient in use.

Another object of the invention is to provide an improved window-chairwhich may be readily set up or removed, and when not in use, may befolded so as to occupy but little space in transportation or storage.

Another object of the invention is to provide a laterally extensiblewindow chair which may be readily adjusted for use in connection withwindows of varying widths, and when set up will not indent, scratch, orotherwise mar any portion of the window frame with which it isconnected.

\Vith these ends in view, the invention consists in the novelconstruction, arrangement, and combination of parts, hereinafterdescribed, illustrated in the accompanying drawings, and particularlypointed out in the appended claim.

Referring now to the drawings, forming a part of this specification,Figure 1, is a perspective view of the improved windowchair as itappears in its normal or operative position applied to an ordinarywindow. Fig. 2, a side elevation of the same, the upper portion of oneof the frame-engaging standards being broken away for the purose ofclearer illustration of the parts. Fig. 3, a detail perspective view ofthe inner abutting or padded side of one of the frameengaging standardsand the pivoted and reinforced ledge-bearing portions of one of the sidebars of the frame of the improved chair-platform. Fig. i, a plan view ofa laterally-extensible form of chair-platform adapted for useinconnection with windows of varying width.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The improved window-chair comprises a pair of laterally-extendingwindow-frameengaging standards adapted to take over and abut against theinner or face sides ofthe vertical or upright members of thewindowframe, and carry a pivotally-mounted chairplatform adapted in itsnormal or operative position to project outwardly through the windowopening and resting upon the win dow sill and ledge portions of thewindowframe to which it is applied, as hereinafter fully described.

The frame-engaging standards 1, are provided at their inner edges withbearing-lugs 2, and link-eyes 8, said bearing-lugs 2, carrying ahorizontally arranged pivot bearing shaft 1, pivotally connecting andsupporting the chair-platform by passing through bearing-lugs 5, at therear or base portions of the chair-platform. As a means of stopping andmaintaining the chair-platform in its horizontal position and at rightangles to the frame-engaging standards, the hearing lugs 5, are providedwith upwardly and laterally extending bracelugs or arms 6, which areadapted to be brought into engagement with the adjacent inner marginaledges of the standards 1, when the chair-.

platform is brought to its horizontal or normal position as indicatedmost clearly in Figs. 1 and 8,0f the drawings.

The chair-platform comprises a frame consisting of side bars 7 connectedby end bars 8, preferably formed integral with each other as shown inFigs. 1, 2, and 3, of the drawings, said side bars 7, carrying aplurality of cross-bars 9, of any suitable and convenient form.

The link-eyes 3, of the frame engaging standards carry brace-chains 10,connected to the free ends of the side-bars 7 in the present instance,by means of hooks 11, taking into eyes 12, near the outer or free endsof the sidebars 7 and adapted to carry the weight of the occupant of thechair-platform.

As a means of firmly securing the windowchair in its connected positionwith the window-frame and particularly as against any rearward movementof the chair-platform when occupied, the side bars 7, are provided withreinforced ledge-bearing portions '13, having a pluralityof vertical pinopenings 14. The pin-openings 14 are adapted to receive and containbrace-pins 15, extending beneath the ledge-bearing portions 13, of theside bars and abutting against the outer or face side of the windowledge16, as shown most clearly in Figs. 1 and.2,.of the drawings. It will beobserved that the plurality of pin openings adapt the chair-platform tobeadjusted to window sills and ledges of varying thickness.

As a means for preventing the marring of the face sides of the verticalmembers of the window-frame the inner or abutting sides of the frameengaging standards are provided with pads 17, of any suitable andconvenient resilient material, preferably, of felt, rubber, or similarmaterial.

As a means for adapting the window-chair for use in connection withwindows of varying widths a laterally-extensible chair-platform may beprovided as indicated in Fig. 4, of the drawings, by means ofoverlapping slidably-connected connecting bars 8 and cross bars 9 saidconnecting and cross-bars having their ends provided with sleeves 18,slidably engaging the contiguous bars, as indicated.

From the foregoing description, taken in connection with theaccompanying drawings, the operation and advantage of my invention willbe readily understood.

Having thus described by invention, what I claim and desire to secure byLetters Pattent is,

A window-chair, comprising cushioned frame-engaging standards providedat their upper inner edges with link-eyes and at their lower inner edgeswith bearinglugs, a chairframe comprising side bars provided with aplurality of pin-openings and terminating at their rear in bearing-lugshaving upwardly and laterally-extending brace-lugs adapted to normallyengage said standards above their bearinglugs, a horizontal bearingshaftpassing through said bearing-lugs of said standards and chair-platform,bracepins mounted in said pin-openings and eX- tending beneath said sidebars, and bracechains secured at one end to the free ends of said sidebars of said chair and at the other to said link-eyes at the upper inneredges of said frame-engaging standards.

In testimony whereof I have affixed my signature, in presence of twowitnesses.

JOHN M. J. SKELLY.
